BLG vs T1 MSI Game 4: Jarvan IV Gamble Shapes the Draft

T1 chose to challenge the draft with Oner on Jarvan IV into Xun’s Skarner, and that decision sets the tone for the entire map. Jarvan IV sits at 37.5% MSI WR in 8G, while Skarner is 100.0% at MSI in 2G for this event and carries a far stronger recent tournament aura. If T1 make that pick work, it will be through sharp early timings, Faker’s priority, and Keria creating chaos before Bilibili Gaming’s front-to-back setup stabilizes.

Compositions

Bilibili Gaming drafted a comp with clear layered engage and side-lane pressure: Bin on Gwen, Xun on Skarner, Knight on Aurora, Viper on Caitlyn, and ON on Elise support. The shape is unusual but coherent. Gwen gives split-push and anti-frontline damage, Skarner supplies hard engage, Aurora adds skirmish control, and Caitlyn can convert lane pressure into tower tempo. Elise support is the real curveball, pushing BLG toward pick-heavy mid game sequences rather than pure 5v5 scaling.

T1 answered with Doran on K'Sante, Oner on Jarvan IV, Faker on Ahri, Peyz on Mel, and Keria on Pyke. This is a much more volatile red-side composition than the pre-draft read from last night, which highlighted T1’s broad access to Vi at 91.7%, Jayce at 91.7%, Azir at 84.6%, and Xin Zhao at 83.3%. None of those comfort-value anchors appear here. Instead, T1 drafted for roam, catch, and reset-heavy fights, with Ahri and Pyke enabling Jarvan IV to force skirmishes before BLG’s carries can set formation.

Key Picks and Stats

Top lane is the clearest statistical edge for Bilibili Gaming. Bin’s Gwen owns a 55.6% global WR over 270G, and the matchup into K'Sante is even better at 66.0% over 47G. On the other side, Doran’s K'Sante sits at 44.6% global WR over 865G, 0.0% MSI WR in 1G, and only 34.0% vs Gwen over 47G. That gives BLG a real side-lane threat if Bin gets space.

The jungle duel is the article’s center. Xun’s Skarner has a 52.0% global WR over 269G and 100.0% MSI WR in 2G, but the direct matchup says 31.8% vs Jarvan IV over 22G. T1 are betting on that exact interaction. Even so, Oner’s champion profile is mixed: Jarvan IV is 51.6% global over 1026G, 37.5% MSI in 8G, though Oner himself is 100.0% on Jarvan IV at MSI in 1G with 4.7 KDA. That makes the pick both targeted and risky.

Mid lane slightly favors T1 on paper. Knight’s Aurora is only 43.1% global over 766G and 33.3% MSI in 3G, while Faker’s Ahri is 53.4% global over 639G and 66.7% MSI in 3G. The direct lane data also leans red side: Aurora is 44.0% vs Ahri over 141G, while Ahri is 54.6% vs Aurora over 141G.

Bot lane is more split. Viper’s Caitlyn brings 55.1% global WR over 528G and is 66.7% vs Mel over 21G, while Peyz’s Mel is only 41.6% global over 245G and 28.6% vs Caitlyn over 21G. Yet Peyz has made the pick work at MSI: 100.0% in 5G, and specifically 100.0% in 2G with 7.5 KDA. Keria’s Pyke at 54.1% global over 109G and 100.0% in 1G at MSI with 3.4 KDA adds roam pressure that can offset the raw lane numbers.

Draft Edge

Compared with the pre-draft analysis, this draft did not confirm the expected T1 value route at all. The forecast suggested T1’s advantage came from flexible, high-WR staples and that Bilibili Gaming’s real levers were Gnar, Bard, Ryze, and Jarvan IV. Instead, BLG moved into Gwen-Skarner-Caitlyn with Elise support, and T1 passed on their cleanest statistical comfort picks for a more explosive setup.

That leaves Bilibili Gaming with the cleaner front-to-back win condition and the more reliable top-side matchup. T1, however, have the sharper first-move tools: Ahri charm angles, Pyke roam windows, and Jarvan IV engage can snowball the map if Faker and Keria unlock side lanes early. Draft edge goes slightly to T1 only if they control tempo first; otherwise BLG’s structure should age better.

Polymarket Market

Polymarket is the strongest external signal here, and it is more skeptical of T1 than the draft model is. The Game 4 market is Bilibili Gaming 50% — T1 50%, while the Series market now is Bilibili Gaming 70% — T1 30%. Pre-match, the Series market was Bilibili Gaming 51% — T1 49%, so BLG have moved +19.5 puntos porcentuales in series pricing since before the match.

That gap matters. The market is saying this specific game is much closer than the overall series position suggests, even with BLG already up after G2 and G3. That makes sense: Bilibili Gaming carry momentum from 20-7 in 29:06 and 14-3 in 33:57, but this draft gives T1 more playmaking volatility than a standard losing position usually would. In other words, the series money respects BLG’s scoreboard advantage, while the single-game market still sees T1’s red-side tools as live.

Prediction

The model opened at Bilibili Gaming 45% — T1 55%, and I would only trim that slightly toward the middle: Bilibili Gaming 47% — T1 53%. T1’s Ahri-Pyke-Jarvan IV trio gives them more early-map agency than the raw MSI Jarvan IV number suggests, but Bilibili Gaming have the stronger top matchup, the more dependable front line, and the series momentum after winning G2 and G3. If T1 do not create an early snowball, BLG’s draft should become easier to execute.
